Letters Patent No. 105,841,1lated J'uly 26, 187th IMPRQVEMENT 1NSTEAM-ENGINE GofvERNoRs.

,l The Schedule referred.` to in these Letters Patent andmaking part pfthe same.

To all whom it may concern y Be it lknown that I, WILLIAM H. PLACE, ofthe city, county, and State of New York, have invented certain new anduseful Improvements' in`Governors for Steam-Engines; and I do herebydeclare that the 4 following is a fulland exact description ofthe same,reference being had to the accompanying drawing and to the letters ofreference marked thereon, in which.

Figure 1 is a vertical section; Figure 2, a plan view; l v `Figure 3, avertical section; and Figure/4, a plan view.v z v Similarlettersofjrcference are employed in each of the iigured drawings." My inventionrelatesto that class of'engine-governorswhich have a propeller orfan-wheel to govern audtregulate thethrottle-valve of a steam-engine, bythe'said;propeller or fan-wheel moving in watery, or

otherliqnid, and by which the increased or didiin.-

islied rotation of the lpropeller or fam-Wheel shall Vbe so elevated ordepressed as to close, in the one ease, the tliiottlea'alve, to checkthe motion of the engine,

` .i shaft .can beelevated or depressed (as required) inless time thancould beV effected otherwise; it being a requirement that the saidmovement should'be made at the moment that a change in the motion of theengine is made, so that the change inthe movement of' the governorshould immediatelybe transmitted to the'throttle-valve. Unless this isdone, the governor would be praeticallyvalueless. f

O is the case ot' the governor, in rwhich is placed the propeller orfan-Wheel D, the propeller being operated from the engine to which thegovernor is at,- t-ached by means of the ,pulleyli aud gear-wheels Gand-H, the pulley F being operated from the main shaft of lthe engine towhich the governor is attached, by means of a cord `or belt, as shallbev found most convenient.` Y

'A is the shaft driving thepropeller or fau-wheel, which is providedwith two sets ofictionwheels, 1 1

and 2 2, as shown, the purpose 'of these frictionwheels being to lessenthe friction of the shaft A in its upward and downward movement throughthe space provided for it, so that it shall act more readily and quicklyfor the purpose' desired than it would do -if placed and operated in thesame space without them. B B, 85e., are ribs placed in the interior'ofthe case Y C, which are placed and located at such angle to thepropeller-wheel D, and in opposite direction to the angle of thepropeller-blades, that they tend to keep the watenor other liquid, inthe interior ofv the case O, during the rotation of the propeller-wheelVD, in` nearly a `solid state, their purpose being to throw back onto thepropeller-'wheel D the water that is thrown off by the latter in itsrevolution, so as toetfect the object before named.

I is a lever, attached by proper connection to the head of the shaft A,which is connected with the' throttle-valve of the engine, for thepurpose of con-v trolling and vgoverningthe valve, and through that themotion of theengne.

The movement of the propeller-wheel D is so gov-v emed inrelation to itsconnection with the throttlevalve of the engine, through the meansnamed, as to4 close the throttlevalve when it reaches its highest pointin the case (l, and to open the same when it reaches its lowest point,the .idea being that, when the governor is properly speeded,v thegoverning' power for a steady motion 'of the engine should be aboutmidway of these two points.

I am aware that in the patent granted to Kenton K. Huntoon, December 5,1866, and reissued December 14, 1869, there are shown bars in thechamber when the propeller or fan-wheel is inclosed, but the bars, asshown, are made vertical, and dofnot and can'- not effect the purposesof the spiral bars shown by me in the drawing, and described in thisspecification.

-I therefore disclaim the right to the said bars, unless they areappliedin the form. and -manner herein set forth.

--What I claiml as my invention, and desire'to secure` 1. Thecombination of the propeller-wheel D with the ribs B B B, 85o., as shownand described andl for the purposes set forth.

2. The friction-rollers 1 1 and 2 2, lin combination
